Struct StdFs 

pub struct StdFs;

ReadStorage over the process filesystem (std::fs).

Reads only. The matching Storage implementation — everything that changes a byte — is prov-store’s, so this adapter is writable exactly when that crate is in the dependency graph.

The trait is async so that genuinely async backends (network, OPFS) fit; this adapter’s futures are immediately ready, so any executor — including the dependency-free crate::exec::block_on — drives them to completion in a single poll.

Trait Implementations

impl Clone for StdFs

fn clone(&self) -> StdFs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for StdFs

impl Debug for StdFs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StdFs

fn default() -> StdFs

Returns the “default value” for a type.

impl ReadStorage for StdFs

async fn read(&self, path: &Path) -> Result<Vec<u8>>

Read the entire contents of a file as bytes. Mirrors std::fs::read.

async fn read_to_string(&self, path: &Path) -> Result<String>

Read the entire contents of a file as a string. Mirrors std::fs::read_to_string.

async fn read_dir(&self, path: &Path) -> Result<Vec<DirEntry>>

Return the entries in a directory (non-recursive). Mirrors std::fs::read_dir, but yields a Vec since async iterators are not yet stable.

async fn metadata(&self, path: &Path) -> Result<Metadata>

Return metadata about the entry at path. Mirrors std::fs::metadata; follows symlinks.

fn try_exists(&self, path: &Path) -> impl Future<Output = Result<bool>>

Returns Ok(true) if the path exists, Ok(false) if it does not, and Err(_) if the check itself failed. Mirrors std::fs::try_exists.
